How much memory and CPUs did you assign to VM? don't go beyond 4/4 unless the game system requirements are higher than that.Ĭheck mac Activity monitor for CPU/memory huggers besides parallels. so I'd put vsync theory aside and start with the basics. btw, macOS APIs, unlike Windows, lack actual vsync control. disabling vsync may help a bit at the expense of tearing effects, but that's not the solution. I just discovered the website 'VsyncTester' Web browser 'VSYNC synchronization', display Hz, and input lag tester () and here are the results.įirst and foremost: stuttering is primarily caused by insufficient (peak) performance. Tried to mess with the Parallels settings, number of cores, memory, disabled full screen optimizations, nothing.My guess : It's a Vsync issue on the Parallels Graphics Driver and it's systemwide. and more.Most of these games runs fines on a low end computer and I've tried running them at low resolution, running my VM desktop in low res (even 800圆00.) and it doesn't change anything.

I'm using the latest Parallels Desktop 16.5 / M1 build on a MBA M1 8g.I'm very picky to stuttering and I immediately noticed something wasn't right on all of my 2D games, there's some constant stuttering on any camera pans / screen movement, and even if the games runs at stable 60 fps stuttering is all over the place in full screen, windowed fullscreen and windowed mode (but with different results on each mode).Games tested : Foregone, Naruta Boy, Skul, Smelter.
